Here's a table that I just made, using data from the
DCL website. I looked at cruises on the Wonder, Dream, and Wish. Bold entries are the largest cabins of a type, italic entries are the smallest. A --- means that the category isn't offered.
| MAGIC CLASS | DREAM CLASS | TRITON CLASS |
INSIDE | 184 | 169 | 169 |
DELUXE INSIDE | 214 | 204 | --- |
OCEANVIEW | 214 | 204 | 218 |
FAMILY OCEANVIEW | --- | 241 | 237 |
VERANDAH | 268 | 246 | 243 |
FAMILY VERANDAH | 304 | 299 | 284 |
So, almost no changes from the Dream class except that the family verandah lost another 15 square feet and the ocean view gained 14 square feet. The deluxe inside rooms were eliminated. The standard inside rooms on the Wish are exactly the same size as the standard inside rooms on the Dream class ships.
If you want to complain about lost size, then you should be complaining about the Dream class. Every category of rooms there is smaller than on the Magic class ships. The Wish just kept things mostly the same.
